(Configuration of information processing system)
Hereinafter, an information processing apparatus and a program according to an embodiment will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiment.

First, an information processing system 1 according to an embodiment will be described using Figure 1. Figure 1 is a block diagram showing an example configuration of an information processing system 1 according to an embodiment.

The information processing system 1 includes a data collection device 2 and an information processing device 3. The data collection device 2 and the information processing device 3 are communicatively connected via a communication network N such as the Internet. In the information processing system 1, multiple data collection devices 2 are communicatively connected to the information processing device 3.

The data collection device 2 is, for example, an in-vehicle device. The in-vehicle device is, for example, a drive recorder. Here, we will explain an example in which the data collection device 2 is a drive recorder 2.

The drive recorder 2 includes an on-board camera (not shown). The on-board camera includes, for example, a lens and an imaging element. The imaging element is a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor). The on-board camera is installed in a position where it can capture images of the areas in front of, behind, to the left, and to the right of the vehicle. Multiple on-board cameras may be installed. The on-board camera captures images of the vehicle's surroundings. The images are moving images.

The drive recorder 2 collects data related to vehicle events. Data related to vehicle events includes at least one of data related to vehicle accidents and data related to reckless driving.

Vehicle accidents include collisions between your vehicle and another vehicle, self-inflicted damage to your vehicle, and collisions between your vehicle and a person.

Dangerous driving is driving that does not result in a vehicle accident, but has the potential to lead to a vehicle accident. For example, dangerous driving includes sudden braking and sudden steering.

Data related to vehicle events includes data that may be factors that cause a vehicle event. Factors that cause a vehicle event are factors that may cause the event to occur when a vehicle event occurs. Factors that cause a vehicle event include, for example, the color of traffic light, the vehicle's speed, and the vehicle's brake operation state. Note that factors that cause a vehicle event include at least one of the color of traffic light, the vehicle's speed, and the vehicle's brake operation state.

The drive recorder 2 identifies traffic lights and further identifies the color of the lights of the identified traffic lights by, for example, performing predetermined image processing based on image data captured by an in-vehicle camera.

The drive recorder 2 acquires the vehicle speed from a vehicle speed sensor (not shown), for example, via CAN communication. Based on the acquired vehicle speed, the drive recorder 2 determines whether the vehicle is complying with the legal speed limit. That is, the drive recorder 2 determines whether the vehicle's speed state is below the legal speed limit, thereby complying, or whether the vehicle's speed state is above the legal speed limit, thereby violating the limit. The drive recorder 2 acquires the legal speed limit for the road on which the vehicle is traveling based on the vehicle's position information, and determines whether the vehicle is complying with the legal speed limit. The vehicle's position information is received, for example, from a GPS (Global Positioning System) device. The legal speed limit for the road is stored, for example, linked to map information.

The drive recorder 2 acquires a signal related to the brake operation state from a brake sensor (not shown), for example, via CAN communication. The brake operation state includes an operation state in which the brake pedal is depressed and a non-operation state in which the brake pedal is not depressed. For example, if the amount of depression of the brake pedal is greater than a predetermined depression amount, the brake operation state is determined to be an operated state. If the amount of depression of the brake pedal is equal to or less than the predetermined depression amount, the brake operation state is determined to be a non-operation state.

The drive recorder 2 stores data related to vehicle events, linking it to the date and time the data was acquired. The drive recorder 2 stores data related to vehicle events for a specified storage time. The specified storage time is a pre-set time, for example, 10 seconds. When the drive recorder 2 acquires data related to new vehicle events, it sequentially erases data related to older vehicle events and updates the data related to vehicle events for the specified storage time.

The drive recorder 2 also stores vehicle environmental data and vehicle driving data, linking them to the date and time the data was acquired. The drive recorder 2 stores vehicle environmental data for a specified storage time and vehicle driving data for a specified storage time. The drive recorder 2 updates the vehicle environmental data and vehicle driving data, as well as data related to vehicle events.

Vehicle environmental data includes weather information and brightness information around the vehicle. The drive recorder 2 obtains weather information, for example, from an external information server (not shown). The drive recorder 2 also obtains brightness information around the vehicle from an illuminance sensor (not shown), for example, via CAN communication. The vehicle environmental data may also include temperature.

The vehicle driving data includes the lighting status of the vehicle's headlights (not shown), vehicle speed information, vehicle acceleration information, and vehicle position information. The drive recorder 2 acquires a signal related to the headlight lighting status from a sensor that detects the headlight lighting status via CAN communication, for example. The drive recorder 2 acquires a signal related to the vehicle's acceleration from an acceleration sensor (not shown) via CAN communication, for example.

When a predetermined transmission condition is met, the drive recorder 2 transmits data related to vehicle events for a predetermined storage time, vehicle environmental data for a predetermined storage time, and vehicle driving data for a predetermined storage time to the information processing device 3 via the communication network N. The drive recorder 2 is equipped with a communication device (not shown) for transmitting data related to vehicle events, etc. to the information processing device 3. When a predetermined transmission condition is met, the drive recorder 2 transmits data related to vehicle events for a predetermined storage time before and after the time the predetermined transmission condition is met to the information processing device 3.

Specifically, when a predetermined transmission condition is met, the drive recorder 2 transmits to the information processing device 3 data related to vehicle events for a predetermined storage time, vehicle environmental data for a predetermined storage time, vehicle driving data for a predetermined storage time, the date and time when each data was acquired, and image data for a predetermined storage time, linked to a device ID assigned to the drive recorder 2. The device ID is identification information that identifies the drive recorder 2. The device ID may also be linked to information about the vehicle in which the drive recorder 2 is installed, information about the vehicle owner, etc.

The specified transmission condition is a condition that determines that an event has occurred in the vehicle. When the vehicle acceleration exceeds a predetermined acceleration, the drive recorder 2 determines that a vehicle accident has occurred and that the specified transmission condition is met.

In addition, if the increase in brake pedal depression per unit time is equal to or greater than a predetermined increase, the drive recorder 2 determines that a sudden braking operation has occurred and that dangerous driving has occurred. The increase in brake pedal depression is calculated based on a signal obtained from the brake pedal sensor.

The drive recorder 2 determines that a sudden steering operation has occurred and that dangerous driving has occurred when the amount of steering operation per unit time is equal to or greater than a predetermined amount. The amount of steering operation is detected, for example, by a steering angle sensor (not shown). The drive recorder 2 may also determine that a sudden steering operation has occurred and that dangerous driving has occurred when the vehicle speed is equal to or greater than a predetermined vehicle speed and the amount of steering operation per unit time is equal to or greater than a predetermined amount.

(Configuration of information processing device)
Next, the information processing device 3 will be described with reference to Fig. 2. Fig. 2 is a block diagram showing an example of the configuration of the information processing device 3 according to the embodiment.

The information processing device 3 is, for example, a server provided for analyzing the cause of an accident. The information processing device 3 displays the analysis results on a display device 4 (display unit). The information processing device 3 is connected to the display device 4 wirelessly or via a wired connection. The display device 4 is, for example, a monitor. The display device 4 may also be a terminal device such as a smartphone.

The information processing device 3 includes a communication unit 10, a control unit 11, and a memory unit 12.

The communication unit 10 is realized, for example, by a NIC. The communication unit 10 receives data related to vehicle events from the drive recorder 2 via the communication network N.

The storage unit 12 corresponds to RAM (Random Access Memory) or flash memory. The RAM and flash memory store information about various programs and data related to vehicle events received by the communication unit 10.

The control unit 11 includes an acquisition unit 20, a setting unit 21, a generation unit 22, and an instruction unit 23. The control unit 11 includes, for example, a computer having a CPU (Central Processing Unit), ROM (Read Only Memory), RAM, a hard disk drive, input/output ports, etc., and various other circuits.

The computer's CPU functions as the acquisition unit 20, setting unit 21, generation unit 22, and instruction unit 23 of the control unit 11, for example, by reading and executing programs stored in a storage device such as ROM.

Furthermore, at least some or all of the acquisition unit 20, setting unit 21, generation unit 22, and instruction unit 23 of the control unit 11 can be configured using hardware such as an ASIC (Application Specific Integrated Circuit) or FPGA (Field Programmable Gate Array). Furthermore, the acquisition unit 20, setting unit 21, generation unit 22, and instruction unit 23 may be integrated or further divided into multiple units.

The acquisition unit 20 acquires data related to vehicle events via the communication unit 10. The acquisition unit 20 accepts input from an operator via a keyboard or the like. The operator is, for example, a person who performs analysis of vehicle events using the information processing device 3.

Specifically, the acquisition unit 20 acquires input related to the vehicle to be analyzed. The acquisition unit 20 accepts, for example, an input result related to the device ID of the vehicle to be analyzed. The input result may be vehicle information linked to the device ID, owner information, etc. If there are multiple vehicles to be analyzed, the acquisition unit 20 may accept input results related to multiple vehicles. The acquisition unit 20 also accepts input results related to the display mode, which will be described later.

The setting unit 21 sets the display mode to be displayed on the display device 4 to the first display mode or the second display mode based on the input result. The setting unit 21 sets the display mode to the first display mode or the second display mode based on the input result regarding the display mode selected by the worker.

The first display mode is a mode in which the occurrence elements of vehicle events are displayed on a map. The second display mode is a mode in which the occurrence elements of events are displayed in chronological order as a graph on the display device 4. The display mode can be changed between the first display mode and the second display mode.

The first display mode also includes a display mode for each occurrence element of a vehicle event. Specifically, the first display mode includes a traffic light display mode, a speed display mode, and a brake operation display mode. The traffic light display mode is a display mode that shows the color of the traffic light. The speed display mode is a display mode that shows the speed status. The brake operation display mode is a display mode that shows the operation status of the brake pedal.

When the display mode is the first display mode, the setting unit 21 further sets the display mode to one of the signal display mode, speed display mode, and brake operation display mode based on the input results regarding the display mode selected by the operator.

When the display mode is the first display mode, the setting unit 21 may set multiple display modes from among the signal display mode, speed display mode, and brake operation display mode based on the input results regarding the display mode selected by the worker. In other words, the setting unit 21 can simultaneously set multiple display modes from among the signal display mode, speed display mode, and brake operation display mode in accordance with the worker's selection. In this case, the display device 4 displays in multiple display modes.

The generation unit 22 generates display data to be displayed on the display device 4 based on the input results. The display data is data that is displayed as an image on the display device 4. The display data includes data related to events of the vehicle to be analyzed. The generation unit 22 reads data related to events of the vehicle to be analyzed from the storage unit 12 based on the input results. If there are multiple vehicles to be analyzed, the generation unit 22 reads data related to events of each vehicle to be analyzed from the storage unit 12. The generation unit 22 generates display data for the first display mode and display data for the second display mode for events of the vehicle to be analyzed.

For example, the display data may include data for displaying a map image including the location where the vehicle event occurred, data for displaying a camera image including the time when the vehicle event occurred, and data for displaying the time when the vehicle event occurred.

The display data also includes data that displays the weather when a vehicle event occurs, data that displays the lighting status of the vehicle being analyzed, and data that displays the brightness around the vehicle being analyzed.

The display data for the first display mode includes data for displaying the selected status of the traffic light display mode, speed display mode, and brake operation display mode. The display data for the first display mode includes data for showing the status of the occurrence element of a vehicle event on the map in different display formats depending on the status of the occurrence element.

The display data for the second display mode includes data that graphically displays the status of vehicle event occurrence factors along the timeline of the occurrence factors.

The instruction unit 23 transmits display data corresponding to the display mode set by the setting unit 21 to the display device 4, causing the display device 4 to display the display data.

Specifically, when the display mode is the first display mode, the instruction unit 23 displays the occurrence elements of the vehicle event on the map in different display forms depending on the state of the occurrence elements of the vehicle event.

Furthermore, when the display mode is the second display mode, the instruction unit 23 displays the occurrence elements of vehicle events in a graph in chronological order, with different display forms depending on the state of the occurrence elements of vehicle events.

(Display image)
Next, the display image 100 displayed on the display device 4 based on the display data will be described with reference to Figs. 3 to 6. Fig. 3 is an example of the display image 100 in the traffic light display form of the first display mode. Fig. 4 is an example of the display image 100 in the speed display form of the first display mode. Fig. 5 is an example of the display image 100 in the brake operation display form of the first display mode. Fig. 6 is an example of the display image 100 in the second display form.

The display image 100 displayed on the display device 4 based on the display data includes a map 30 of the location where the vehicle event occurred, video 31 of the vehicle event captured by the drive recorder 2, and the date and time 32 when the vehicle event occurred. The display image 100 displayed on the display device 4 based on the display data also includes the weather 33 when the vehicle event occurred, the lighting status 34 of the vehicle being analyzed, and the brightness 35 around the vehicle being analyzed. By displaying the weather 33 when the vehicle event occurred and the like on the display image 100 of the display device 4, the operator can more accurately know the circumstances under which the vehicle event occurred.

If there are multiple vehicles to be analyzed, the vehicle lighting status 34 displays the lighting status of the selected vehicle. In Figure 3 and other figures, the selected vehicle is shown in black.

The display image 100 based on the display data for the first display mode also includes a selection state 40 for the traffic light display mode, speed display mode, and brake operation display mode. The display image 100 based on the display data for the first display mode also includes occurrence elements of vehicle events. The occurrence elements of vehicle events in the first display mode are displayed on the map in different display forms depending on the state of the occurrence element.

When the first display mode is the traffic light display mode, as shown in Figure 3, lines 50a, 50b indicating the color of traffic lights related to a vehicle event are displayed on the map in a display format that differs for each traffic light color. The lines 50a, 50b indicating the color of traffic lights are displayed on the map in association with the traffic light color and the vehicle's position.

The lines 50a, 50b indicating the color of the traffic light are displayed in different types according to the color of the traffic light. The lines 50a, 50b indicating the color of the traffic light are displayed, for example, in different types of lines according to the color of the traffic light. Note that the lines 50a, 50b indicating the color of the traffic light may also be displayed in different colors, thicknesses, etc. according to the color of the traffic light.

When the first display mode is the speed display mode, as shown in Figure 4, lines 51a and 51b indicating the vehicle speed state related to a vehicle event are displayed on the map in different display modes depending on the speed state. Lines 51a and 51b indicating the vehicle speed state are displayed on the map in association with the vehicle's speed state and the vehicle's position.

The lines 51a, 51b indicating the vehicle's speed state are displayed differently depending on whether the vehicle's speed state is in compliance with the speed limit or in violation. The lines 51a, 51b indicating the vehicle's speed state are displayed, for example, using different types of lines depending on the vehicle's speed state. Note that the lines 51a, 51b indicating the vehicle's speed state may be displayed differently depending on the vehicle's speed state using different line colors, line thickness, etc.

When the first display mode is the brake operation display mode, as shown in Figure 5, lines 52a and 52b indicating the vehicle's brake operation status related to a vehicle event are displayed on the map in different display forms depending on the brake operation status. Lines 52a and 52b indicating the vehicle's brake operation status are displayed as lines that associate the vehicle's brake operation status with the vehicle's position.

The lines 52a, 52b indicating the vehicle's brake operation state are displayed differently depending on whether the vehicle's brake operation state is operated or not. The lines 52a, 52b indicating the vehicle's brake operation state are displayed, for example, using different types of lines depending on the vehicle's brake operation state. Note that the lines 52a, 52b indicating the vehicle's brake operation state may be displayed differently depending on the vehicle's brake operation state using different line colors, line thickness, etc.

The display image 100 based on the display data in the second display mode includes a graph in which at least a portion of the vehicle's driving data is displayed in chronological order. The display image 100 based on the display data in the second display mode also includes a graph in which occurrence elements of vehicle events are displayed in chronological order in different display formats depending on the state of the occurrence elements.

For example, as shown in Figure 6, changes in vehicle speed and acceleration (G-value) related to a vehicle event are displayed in a graph over time. Note that Figure 6 shows a diagram in which only changes in speed and acceleration of a selected vehicle from among multiple vehicles are displayed in a graph, but this is not limited to this, and changes in speed and acceleration of unselected vehicles may also be displayed in a graph. Furthermore, either one of changes in vehicle speed and acceleration related to a vehicle event may be displayed in a graph over time. In other words, it is sufficient if at least one of changes in vehicle speed and acceleration related to a vehicle event is displayed in a graph over time.

The colors of traffic light signals related to vehicle events are also displayed in different graphical formats over time. The graphical display of traffic light colors is distinguished by different types of lines corresponding to the color of the traffic light. The graphical display may also be distinguished by line color and line thickness, etc., according to the color of the traffic light.

In addition, the vehicle's speed status related to vehicle events is displayed in a graph in different display formats over time. The vehicle's speed status is displayed with different types of lines depending on whether it is in compliance or noncompliance. The vehicle's speed status may also be displayed with different line colors and line thicknesses depending on whether it is in compliance or noncompliance.

In addition, the vehicle's brake operation state related to vehicle events is displayed in a graph in different display formats over time. The vehicle's brake operation state is displayed using different types of lines to distinguish between an operated state and an unoperated state. The brake operation state may also be displayed using different line colors and line thicknesses to distinguish between an operated state and an unoperated state.

(Data display processing)

(Modification)
The information processing device 3 according to the modified example may simultaneously perform display based on the display data in the first display mode and the display data in the second display mode on the display device 4. That is, the information processing device 3 according to the modified example may display occurrence elements of vehicle events on a map displayed on the display device 4, and may also display the occurrence elements of vehicle events in a graph in chronological order. For example, the information processing device 3 according to the modified example generates display data and transmits the display data to the display device 4 so that the map 30 shown in Figures 3 to 5 is displayed on the map 30 in Figure 6.

As a result, the information processing device 3 according to the modified example can improve the efficiency of checking the occurrence status of vehicle events.

In a variant example, the information processing device 3 may have only one of the first display mode or the second display mode as the display mode.

The information processing system 1 according to the modified example may estimate data related to an event of another vehicle from an image acquired by the drive recorder 2 of a certain vehicle. For example, the information processing system 1 according to the modified example may calculate the speed of another vehicle from the other vehicle that appears in an image acquired by the drive recorder 2 of a certain vehicle, and estimate the speed of the other vehicle. The information processing system 1 according to the modified example may calculate the speed of another vehicle from the other vehicle that appears in a curve mirror in an image acquired by the drive recorder 2 of a certain vehicle, and estimate the speed of the other vehicle. Similarly, the information processing system 1 according to the modified example may estimate the color of traffic lights in the direction of travel of the other vehicle.

As a result, the information processing device 3 according to the modified example can display occurrence elements of events in other vehicles on the display device 4 even if data related to the event is not acquired from the other vehicles.

Furthermore, when the information processing device 3 according to the modified example estimates data related to an event of another vehicle, the estimated occurrence elements of the event of the other vehicle may be displayed on the display device 4, distinguishing them from occurrence elements that are actually obtained from the drive recorder 2 of the other vehicle. For example, the information processing device 3 according to the modified example may display the estimated occurrence elements of the event and the actually obtained event occurrence elements in different display modes.

As a result, the information processing device 3 according to the modified example can distinguish between the estimated occurrence elements of an event and the actually acquired occurrence elements of an event and display them on the display device 4. This allows the worker to easily distinguish between the estimated occurrence elements of an event and the actually acquired occurrence elements of an event.

Furthermore, the information processing system 1 according to the modified example may identify the generating element for the color of the traffic light by the information processing device 3. Specifically, the information processing device 3 according to the modified example identifies the traffic light and further identifies the color of the light of the identified traffic light by performing predetermined image processing on the image data transmitted from the drive recorder 2.

As a result, the information processing system 1 according to the modified example can reduce the processing load on the drive recorder 2.

In addition, the information processing system 1 according to the modified example may include a fixed camera as the data collection device 2. The fixed camera captures images of a predetermined shooting range. The fixed camera is installed, for example, at a street light or on the side of the road. The fixed camera includes, for example, a lens and an imaging element such as a CCD or CMOS. The fixed camera transmits the location of the fixed camera and the captured images to the information processing device 3 via the communication network N. The information processing device 3 according to the modified example acquires occurrence elements of vehicle events from the images captured by the fixed camera.

This allows the information processing device 3 according to the modified example to collect a large amount of information about vehicle events. This allows the worker to more accurately understand the status of vehicle events.

The above embodiments and variations may be applied in combination.

Further advantages and modifications may readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
